I'm a C#.Net developer and haven't done VBA in a long time, so forgive my ignorance.

I have an Access 365 app from a client and I'm trying to work on it off site. I have Office 2013. When I open the app I get the error "Can't find project or library" on this line:

Dim appOutlook As Outlook.Application
If I uncheck the missing references won't this break the code once it's back at the client site? Again , they're referencing Office 365.

In the references list I'm missing:
  • Microsoft Office Outlook 16.0 Object Library
    Microsoft ActiveX Data Objects 2.0
    Microsoft Office Excel 15.0 Object Library
    Microsoft Office 15.0 Object Library

1) If I remove these references, won't that break things back on the the client's site?
2) How do you normally handle a situation like this?

Thank you
